Embodiment 1
[0027] The first batch of production specifically includes the following steps:
[0028] a. Ammonification: Mix 228.06 g of hydroxyacetonitrile and 1175 g of ammonia water with a concentration of 23% by mass (the molar ratio of hydroxyacetonitrile to ammonia is 1:4), and pump it into a tubular reactor at a temperature of 83°C and a pressure of Under the condition of 1.3MPa, the ammoniation reaction was carried out, and the reaction time was adjusted to be 6 minutes by controlling the flow rate to obtain the aminoacetonitrile reaction solution;
[0029] b. Alkaline hydrolysis: Add 351.82 g of sodium hydroxide solution with a mass percent concentration of 50% in advance in the alkaline hydrolysis reactor (the molar ratio of sodium hydroxide to hydroxyacetonitrile is 1.1:1), and use the alkaline hydrolysis reactor in the tubular reaction The aminoacetonitrile reaction liquid is collected at the outlet of the reactor, and the aminoacetonitrile reaction liquid that enters the alk...
